Breakthroughs in Domestic High‑End Valves: Multiple Special Valves Achieve Localized Substitution

In 2026, the localization of high‑end domestic valves continues to accelerate. Many bottleneck‑breaking special valves for nuclear power, coal chemical, oil‑gas and ultra‑supercritical thermal power have passed technical appraisal and been applied in real‑world projects, breaking long‑term monopolies held by overseas brands.

Nuclear‑grade helium isolation valves, large‑size orbital ball valves and ultra‑supercritical secondary reheat bypass valves have obtained national‑level industry appraisal, manufacturing licenses and been put into service. Under harsh working conditions such as high temperature, high pressure and strong corrosion, their performance matches international counterparts, greatly cutting procurement costs and shortening delivery risks for major domestic projects.

Driven by national policies for independent‑controlled major equipment, local valve manufacturers are increasing R&D investment, shifting from simple component production to complete high‑end valve solution providers. Competition focus has shifted from low‑price bidding to comprehensive strength including R&D, manufacturing and after‑sales services, delivering reliable localized fluid control solutions for chemical, nuclear power, new‑energy and oil‑gas projects.
